Inputs and Testing Continued...
Below is a wiring example of a typical input circuit, using a Proximity Sensor Switch. The
Proximity Switch has three wires. Blue will connect to negative, Brown to positive, and
Black is the signal which connects to the appropriate PLC Input. The sensor operates when
metal passes by the face. An LED light located on the sensor will indicate operation. The
batteries will supply the 24 Volts. All of the machine's Proximity Sensor Switches are wired
like this; the only difference is that the wires will pass though plugs and junction blocks.
